Washer just hums when time for the water - Washing Machines

Check the water water supply at the water inlet valve. Remove the supply hoses and check that the small screens in the inlet valve are not clogged with rust or debris. The water inlet valve solenoids can be tested using a multimeter or ohmmeter. Check for continuity. A lack of continuity indicates a faulty solenoid and the water inlet valve will need to be replaced. I am attaching a photo for reference. Hope this helped and best wishes.

Chances are the fill solenoid valve has failed and will have to be replaced.
But before replacing any parts, make sure there is a working water supply to the machine and the water inlet screen is not plugged.
Turn the hot and cold water valves off at the washer. Unscrew the water feed line hoses from the washing machine. Using a mop bucket to catch water, turn the cold water valve on to verify water flow, repeat for hot water, turn off water when verified. Then, using a flashlight, look inside the water hose connection on the washing machine.
Check for rust and debris plugging the screens in the machines water inlet. Remove the screens and clean if necessary.
If the water supply appears good, you will want to start checking the water fill valve.
Let me know if I need to go further.
